Method for optimization of mobility awareness in mobile networks

Abstract

The invention relates to a method and a network entity to manage the establishment of data connections of a user terminal allocated in a mobile communications network.

1 . Method for establishing data connectivity for at least one user equipment the method comprising, in a network entity of a mobile telecommunications network, the steps of:
 performing a packet inspection of traffic data generated by the user equipment,   determining whether the user equipment is running a mobility sensitive application said determination being based on an analysis of the traffic data retrieved during the packet inspection,   retrieving QoS data related to said user equipment from a database accessible by said network entity, and   assigning a priority level selected from a plurality of priority levels resulting from the determination of whether the user terminal is found to:
 be in mobility, 
 be using at least one mobility sensitive app, and 
 have a high priority level in the QoS, 
   wherein the method further comprises allocating a bit-rate level to said user terminal according to the priority level assigned to said user terminal, where a higher bit-rate level is assigned to a higher priority level.   
     
     
         2 . Method according to  claim 1  wherein the network entity is a RNC. 
     
     
         3 . Method according to  claim 1  wherein the network entity is a node B where the mobile terminal is allocated. 
     
     
         4 . Method according to  claim 1  wherein the mobility sensitive application is an application that requires a minimum constant bitrate. 
     
     
         5 . Method according to  claim 1  further comprising determining whether the user equipment is in mobility by checking the amount of handovers generated by said user terminal when the packet inspection takes place. 
     
     
         6 . A network entity for establishing data connectivity for at least one user equipment of a mobile telecommunications network, comprising:
 a packet inspector module which inspects the content of data packets of traffic data generated by the user equipment,   a mobility detection unit for determining whether the user equipment is in mobility, access module for accessing subscriber QoS data from a QoS database accessible within the mobile telecommunications network, and   wherein the entity facilitates connectivity at a selected level of QoS, said QoS being determined by the policy table.   
     
     
         7 . Network entity according to  claim 6  wherein the packet inspector module is further adapted to perform a check of an amount of handovers generated by the user terminal. 
     
     
         8 . Network entity according to  claim 6  further comprising a bitrate checker module adapted to determine an application that requires a minimum constant bitrate. 
     
     
         9 . Network entity according to  claim 8  wherein the bitrate checker module comprises a lookup table with a list of sensitive applications.
